1000/23.97 = 41.71ms
1000/29.97 = 33.36ms
1000/59.94 = 16.67ms
etc.
 
You need to use settings which have render times lower than the movie frame interval, and ideally below the vsync time.
The higher the framerate/refresh rate, the less time the GPU has to process the image.

Gotcha.  I noticed that the render time stayed below for the most part, but crept up to 44ms or so.

Been playing with it a little, changed some of the settings, down to about 36ms, but not sure if it's the best use of resources:

Chroma Upscaling - Lanzos 3 tap

Image doubling
  Luma - 16 neurons
  Chroma - 16 neurons

Image upscaling - Lanczos 3 tap

Well, getting this figured out, I think that it's a lot more straight forward than I originally thought.

I do have some questions about the profiles.  I think that they'll do what I want.

When using the tv function, I can't line double, but I can when I'm watching a show.  I think that I should be able to make profiles based on the conditions I'm thinking of.

My question is, are there a few profiles available to look at in order to reduce my learning curve?

There are some details on the profiles here: http://forum.doom9.org/showpost.php?p=1271417&postcount=3

Right now, I'm using:


--- Code: ---if (srcHeight<=360)                      "<SD"
if (srcHeight>360) and (srcHeight<=480)  "NTSC"
if (srcHeight>480) and (srcHeight<=576)  "PAL"
if (srcHeight>576) and (srcHeight<=1080) "HD"
if (srcHeight>1080)                      "UHD"
--- End code ---

Though I really need to update that.

I'm guessing you would use a rule based on srcInterlaced to set different scaling quality depending on whether the source it interlaced or not.

newguy1:
Haven't got to the coding yet, but having fun trying to figure MadVR out!

I'm loving the line doubling by the way, it easily (subjectively) doubles the quality.

What I'm wondering is why my HDHomeRun automatically changes tv to 59.941fps and calls it a movie, any ideas?  I'm guessing that tv should be 30 (or so)fps.
